Embodiment 1
[0056] like figure 1 As shown, the farm louver fan system of the present invention includes a louver fan, and the louver fan is also equipped with the following components:
[0057] The detection device includes a three-axis acceleration sensor, a fan current and voltage acquisition circuit, and a detection circuit, wherein:
[0058] The three-axis acceleration sensor is installed on the louver plate of the air outlet of the louver fan, and is used to detect the angle between the current sensor and the direction of gravity, that is, the angle between the louver baffle and the direction of gravity;
[0059] The fan current and voltage acquisition circuit is placed at the power supply line end of the fan to detect the fan's startup transient current and voltage, as well as the normal operating current and voltage;
[0060] The detection circuit is integrated on the PCB circuit board of the louver fan, and forms a blade attitude detection device with the three-axis acceleration ...
Embodiment 2
[0071] In addition, this application also provides a detection method and a prediction method for a louver fan in a farm, wherein: the detection method for a louver fan in a farm according to the present invention includes the following steps:
[0072] Step 1: Detect whether the louver fan is activated, including two situations:
[0073] Case 1: Detect whether the fan is started: obtain the instantaneous current and voltage of the fan through the fan current and voltage acquisition circuit, and make the following judgments:``
[0074] If the fan current and voltage acquisition circuit can obtain the instantaneous starting current and voltage, then continue to compare and judge with the historical data:
[0075] If the instantaneous current and voltage are consistent with the historical data, proceed to step 2;
[0076] If the instantaneous current is more than 30% larger than the historical data, and the voltage is lower than 30%, it is judged that the fan is abnormal, and an...

[0098] The prediction method of the louver fan in the farm according to the present invention, according to the large database of historical data, constructs the prediction model of the fan and the louver, judges that the fan and the louver are in the stage of the prediction model, and the server advances the predictive guidance conclusion It is transmitted to the control device or environmental controller of the louver fan through the wireless communication module.
[0099] The maintenance method of the louver fan in the farm according to the present invention, the instantaneous process of the starting current detected by the current and voltage acquisition circuit of the fan can determine the aging degree of the fan, the real-time detection of the normal operating current and voltage of the fan, and the spectral analysis and Time domain analysis judges the problem of normal operation of the fan;
[0100] The instantaneous opening angle detected by the three-axis acceleration...
